To @ZZ wim/m it 'muy concern."

Be .it known that L, Wimmer Emis'rus Wim-imite, s eitizen of the UnitedStates, und e' resident of Wilniette, county of Cook, otiliinois, heveinvented e new and us. fui Improvement in Sheet Steel Disk if'ilieeis,of which the following is e speoification.

The Obie-ot et my invention is'to ineke e strong und light ivheei andone that .tney be used for eutoinobiie purposes nud. be adapted `to bedemounted es e Wheel und also to I provide for s deinountsbie rim.

Reference will be had to the accompanying drawings in which Figure l is:t front elevation of the wheei.

Figure 2 is s elevation.

`iigure 3 is e treue verse section of the rim portion on line fir-m3 oulFigure l.

Figure i is is, section similar to that of Figure 3 but 1s taken on lineLi-4e on Figif Fig. l. rensverse section of the hub ii on Figure 2.

The mein web ot Jhe Wheel is mede of 2isheet of motel, sewing :front surface 6 around the liub sone merged intoe concave surface 7- end it in "im merged into e front ieiloe surface 8,end thisusureoe is turned over into sin approximately coriicei flange 9pro vided with. ein outwardly turned marginal edge id which Lfornishesthe support for one edge oi? 'the pueuins tire rim if.

i series of rookies; slips il. ere heid in pisse by screws screwed intofixed nuts 13, and thus tu nsh the sost tor the Airont edge of thepneuiustie rim. iiie ciips 'il ere provided 'with heur-ieg 'port' 'irislei' rest ing on edge of the disk und between the rim 5 sind the disk.

The main disk 'web i ,o or" relatively thin steel reinforced 'oy esecondary disk in 'contact with the .mein

disk at i5 and from thence extending toward the center with its surface1G in Contact with the flange i of the hub. Around the hub barrel thissecondary disk is embossed to forni the inclined annuler portion .i7which is merged into e narrow vertical ienge 18 joined to the mein disket 19.

The secondary disk is stifi'ened across from the surface 16 to its outermargin by u series of eorrugetions 20 which have the eiiect of extendingthe surface 16 at intervals across into Contact with the main disk.

The main disk and the secondary disk are stiiiened across between thesurfaces 6 and 1G by Ineens of a spreader ring- 21, adapted to take thedirect thrust of the clamping bolts 3 under strain of their outer nuts22 which serve to hold the Wheel on the hub. This ring 21, is loopedaround `the bolts 3 as .shown in Figures 6 sind 7 to better sus tuin theplates disks under the strain of the seid boite, und also for thepurpose of taking some oit the torque thrust und thereby relieving themarginal edges of the pistes or disks at vthe peri'orstions for thebolts 3.

rlChe main disk und the ,reinforcing disk .fire spot 'Welded orotherwise suitably sstened at the surface n15 and around the hubaperture et the "rfaces i8 and i9.

The spreader ring' 2l is also spot Welded to the disk on each side, thusrigidly uniting it'to the disks.

The hub here shown is of the general out line used with Wooden Wheels,but 'to eccominodste it for s demounting Wheel purpose, l provideinclined bearing blocks 23, inte gral with 'the hub in order to providee. seat for the inclined annular poizion 17 of the disk.

The modified form, es shown in Figure "I, shows the surface `17 oi" thereinforcing disk provided With'iudentutious24 that embrace the oornersot the portions. or blocks 23 of the hub for the purpose of. taking someof 'the driving',` torque from the bolts 2i..

lThe portion *i of the main disk extends ii'itvnrdly suiiieieu'tiy to'permit the use straight vulve stem of the pneumatic tire, und the diskis perforated on the 'iront i'aee es shown by 25 on Figure 'i undthrough the tread deugt :also ss indicated by 27, Figure 5, the twoperi'orfitions being in line to ede init a straight veive stem which isshown in position by dotted lines in Figure 2.

A portion of the riin dangV 9, see Figures 8, 4 and 5, is embossedinward, as is indicated by the surface '28 in Figure 5, and this portionis perforated at 29 to admit the driv ing lug 30 secured to therim'. Thepurpose of embossing this portion is to lpermit the seating ,of` thecoupling members that con-v rim v5.

nect the'ends vof a split rim, In order -to make'the gap Aas narrow aspossible between `the front corner of the main disk at the f elloe..portionS vand the inside edge of the rim, I provide, as it were, aribbed portion 31 for the depressed portion 28,'but this ribbedportionis wanting or is absent at 32 -for convenience or clearance ofthe lock-f` member of th? end connection of `4thefsplit .What I claim l.1. In a wheel of the class described, the

` web of `the wheel composed of a concave disk reinforced "on the backby a secondary disk terminating in a zone about midway from the hubto-.the rim and -joined thereat to the main web and thence spacedasunder from the main disk web and Aadapted. to

abut laterally against a hub flange,- and from this ange the saidsecondary` disk having an outwardly inclined extending annular zonebearing on inclined bearing surfaces of. the hub body, and the two disksioined together at the apertureof the hub barrel. v

2. In a deviceof the'j class described, a

main disk and a reinforcing disk, the latter covering the zone for Zadistance around the, hub barrel. and the two' disks connected to-Lgether at the outer margin ofthe reinforcing disk and at the aperturearound the hub and spaced apart in. a zone between these points ofconnection, and said reinforcing disk provided with an inclined bearingsurface adapted to register on an inclined surface on the hub barrel, incombination with af separator member lying between the two disks'intheir separated region and adapted to sustain the thrust of clampingbolts in combination with a series of clamping bolts passing throughboth plates and adapted to secure the wheel to the hub.

3. In a device of the class described, a front disk,l forming. the mainweb of the wheel in combination with a reinforcing disk at'the rear offthemain disk 4and the latter formed withinclined bearing surfaces Yadapted to bear upon'and support the main disk and also bear lonanfincllned surface on the hub barrel, the 'two disks spaced apartbetween the said Vbearing regions; in combination withaseparatoreportion acting as a s reader between the-separated areas of.the f isks and this v separator portion looped around the bolt holeslthrough which pass the Bolts which fastenthel disks to the hub, and

a"s'eries of clamping bolts passing throughthe loops on the separatorportion and adaptiedlto hold the disksv to the hubt 4. In a wheel of theclass described, a disk forming the web of the wheel having a verticallydisposed area surroundin the hub barrel, a secondary reinforcing disk atthe rear of the' main disk and joined to the main disk at the hubaperture, and inclined' inward from this junctureand bearing upon fillerspreader composed Jof a flat piece of l. metal loopedaround th#r boltholes, in combination with a Aseries' of y bolts passing through bothdisks and adapted to hold the l same to the hub.

combination with a reinforcing disk connestedV to the main disk andseating on the x',lhlib barrel and provided witlra seriesof en- 6. In alwheel of the class-described, a main disk forming the web ofv the wheelin4 gaglng indentations and the hub barrel proi l vided with a. `seriesof projections 'adapted to be engaged withthe indentations in thereinforcing diskl and thus assist in resistin the torque strains'between the hubV and the isks.
